I got it to work finally!!! From the trigger pin i put a small capacitor to one side of the push button and the other side hooked up to the ground. So when the switch was activated it grounded pin 2 for a couple of milliseconds before the capacitor started charging. Once the capacitor starts charging it brought the trigger pin back to the idle state so there would be no chance of having an inaccurate dwell time.
